Control Banding and the International Chemical Control Kit Pavan Baichoo Programme on safety and health at work and the environment (SafeWork) 20/04/2017

Presentation structure What is Control Banding The International Chemical Control Kit GHS and Control Banding Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Control banding addresses a problem Many chemical hazards in the workplace Employers need guidance on how to protect workers OELs established for relatively few chemicals Availability of technical expertise and monitoring equipment may be limited Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Control banding takes a pragmatic approach Occupational risk assessment and risk management instrument Developed by occupational hygienists and toxicologists Uses readily available information about chemicals and the workplace, to rank hazard and assess risk Can be used without on-site technical experts and expensive exposure measurements Suitable for small and medium sized enterprises (SMEs) Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Control banding has 3 elements Hazard Risk of exposure Control measures Called control banding because these are grouped into bands Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Hazard & risk uses available information To categorise hazard – use existing hazard assessment e.g. EU Risk (R) phrases, GHS classification Risk based on: Amount of chemical used Likelihood that will become airborne Volatility (liquids) or likelihood of dust generation (solids) Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Limited number of control measures Employ good industrial hygiene practice Engineering control e.g. local exhaust ventilation Enclose the process Seek the advice of a specialist Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

International Chemical Control Toolkit Scheme for Workplace Chemicals Control Kit designed for SMEs in developing countries Work undertaken by experts from ILO, IOHA, USA, South Africa, HSE Provides simple means for applying the hazard and risk information to identify the control measure Generic risk assessment based on GHS and task guidance sheets Aim is to provide simple and practical means to prevent/reduce risks of chemicals Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Pavan Baichoo, SafeWork, ILO Geneva Scope Many substances used at work contain chemicals Guidance should be provided to ensure safe handling Does not cover process generated dusts and fumes Based on the HSE’s COSHH Essentials kit Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Pavan Baichoo, SafeWork, ILO Geneva Toolkit operation Five stages: Hazard classification Scale of use Ability to become airborne Finding the control approach Finding the task-specific control guidance sheet(s) Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Hazard classification Determination of hazards presented by the chemicals (based on R phrases or GHS) 6 hazard groups (A-E inhalation, S contact) Simple 3-step reference table allows hazard group to be assigned to the chemical Hazard groups determined for common solvents Set of guidance sheets for pesticides Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Pavan Baichoo, SafeWork, ILO Geneva Scale of use Determines how much is used/handled Quantity Solid Liquid Weight Typically received in Volume Small Grams Packets or bottles Millilitres Bottles Medium Kilograms Kegs or drums Litres Drums Large Tonnes Bulk Cubic metres Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Ability to become airborne Physical form of chemical affects how likely it is to get into the air Solids Low: pellets Medium: crystalline solid High: powder Liquids Low: BP > 150°C Medium: BP 50 – 150 High: BP < 50 Process temperature Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Selection of control approach Stages 1-3 enable the choice of control approach to be made using table 4 control approaches possible: general ventilation, engineering controls, containment and Special Table overleaf allows for easy identification Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Control approach selection Amount used Low dustiness or volatility Medium volatility Medium dustiness High dustiness or volatility Hazard group A Small 1 Medium 2 Large Hazard group B 3 Hazard group C 4 Hazard group D Hazard group E For all hazard group E, substances, choose control approach 4 Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Find the task-specific guidance sheet(s) General guidance sheet for each approach Development of a range of simple and practice task specific control guidance sheets is planned Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017

Find the task-specific guidance sheet(s) Task description Task control sheet Control approach 1 General principles 100 Sack, bottle & drum storage 101 Bulk storage 102 Removing waste from air cleaning unit 103 Pavan Baichoo, SafeWork, ILO Geneva 20/04/2017
